Product details
Overview
BAS16B5000 from Nexperia is a silicon switching diode in SOT23 package, rated for 80 V reverse voltage, 250 mA forward current, and 4 ns reverse recovery time, designed for high-speed signal routing and clamping in automotive and industrial control logic circuits.
For engineers reviewing the BAS16B5000 datasheet, BAS16B5000 pinout, BAS16B5000 application, or BAS16B5000 equivalent, this device supports fast-switching requirements in level-shifting interfaces, ESD-protected I/O buffers, and low-power digital signal conditioning where low capacitance (≤2 pF) and minimal forward voltage (715 mV at 1 mA) are critical.
Technical Context
This diode operates as a single-anode, single-cathode PN junction with A6s marking, optimized for unidirectional transient suppression and signal steering. Its 4 ns trr and ≤2 pF CT enable clean edge transitions in 10–50 MHz digital clock distribution paths.
Qualified to AEC-Q101, it sustains 150 °C junction temperature and delivers stable IR ≤1 µA at 75 V (25 °C), supporting reliable operation in under-hood automotive modules and industrial PLC input stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - Supports rail-to-rail signal clamping up to 24 V systems with 3× safety margin. |
| Reverse Recovery Time (trr) | 4 ns - Enables clean switching in >25 MHz digital signal paths without ringing or overshoot. |
| Diode Capacitance (CT) | ≤2 pF @ 0 V, 1 MHz - Minimizes loading on high-impedance CMOS inputs and RF-sensitive nodes. |
| Forward Voltage (VF) | 715 mV @ 1 mA - Reduces power loss in always-on bias networks and logic-level translators. |
| Junction Temperature (Tj) | 150 °C - Certified for under-hood automotive use per AEC-Q101 stress testing. |
| Thermal Resistance (RthJS) | ≤260 K/W - Allows 370 mW dissipation with modest PCB copper area (≥25 mm²). |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with gull-wing leads, footprint compatible with JEDEC TO-236AB, suitable for automated pick-and-place and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry node | Connected to higher-potential side in clamping or steering configurations. |
| Cathode (Pin 2) | Current exit node | Typically tied to ground or logic reference; defines conduction direction. |
| Collector / Heat Sink (Pin 3) | Package tab / thermal path | Electrically isolated metal pad; used for thermal relief, not electrical connection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics including engine control units and body controllers. |
| Pb-free (RoHS compliant) | Meets EU Directive 2011/65/EU; no lead content in die attach, plating, or molding compound. |
| Low leakage (IR ≤1 µA @ 75 V) | Preserves signal integrity in high-impedance sensor interfaces and battery-backed circuits. |
| Fast trr (4 ns) + low CT (≤2 pF) | Enables sub-10 ns pulse fidelity in serial data lines and microcontroller GPIO protection. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|
Use Scenario: Clamping CAN transceiver I/O pins against ESD and load-dump transients. IC Role / Device Role: Unidirectional transient voltage suppressor and signal conditioner. Use Value: Prevents latch-up in 3.3 V/5 V transceivers while adding <0.5 ns propagation delay. | Use Scenario: Level-shifting 24 V field signals to 3.3 V microcontroller GPIOs. IC Role / Device Role: High-speed interface diode in optocoupler input stage. Use Value: Maintains >10 kHz sampling rate with <1% duty-cycle distortion due to 4 ns trr. |
| USB Port ESD Protection | Low-Power Sensor Signal Conditioning |
Use Scenario: Series protection on D+/D− lines before USB PHY IC. IC Role / Device Role: Low-capacitance signal path switch and clamp. Use Value: Adds only 1.8 pF series capacitance, preserving USB 2.0 eye diagram integrity. | Use Scenario: Biasing and protecting thermistor or RTD bridge outputs. IC Role / Device Role: Precision DC path selector and overvoltage limiter. Use Value: Delivers 715 mV VF stability across −40 °C to +125 °C, enabling <0.1% offset drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS12500U | Higher IF (300 mA), slightly slower trr (6 ns), same SOT23 package. | Better suited for higher-current logic buffering; less ideal for >20 MHz signal integrity. | Select when average forward current exceeds 250 mA but trr tolerance >6 ns is acceptable. |
| Diodes Inc. BAV99LT1G | Dual-series configuration (2 diodes), 3.5 ns trr, 1.25 pF CT, SOT23-3. | Enables differential clamping or dual-rail protection; requires layout revision. | Choose for space-constrained dual-signal paths where shared cathode/anode topology reduces component count. |
Compared with BAS16B5000, NSS12500U trades speed for current headroom, while BAV99LT1G offers superior AC performance at the cost of functional duplication-making BAS16B5000 optimal for single-diode, cost-sensitive, high-frequency signal routing.

FAQ
Is BAS16B5000 pin-compatible with standard SOT23 diodes like 1N4148?
Yes, BAS16B5000 uses the standard SOT23-3 footprint with anode (Pin 1), cathode (Pin 2), and exposed thermal pad (Pin 3). Unlike 1N4148 (DO-35), it is not mechanically or electrically interchangeable due to different internal construction and AEC-Q101 qualification, but PCB layout reuse is possible with thermal pad grounding verification.
What is the maximum allowable continuous forward current at 100 °C ambient?
At TA = 100 °C, the derated forward current is 150 mA, based on the IF vs. TS curve for BAS16 (Sheet 6) and Ptot = 370 mW with RthJS ≤260 K/W. This ensures Tj remains below 150 °C with adequate PCB copper area.
Does BAS16B5000 support bidirectional ESD protection?
No - BAS16B5000 is a unidirectional silicon switching diode. For bidirectional ESD protection, a dedicated TVS array (e.g., PESD5V0S1BA) or back-to-back diode configuration is required. Its design targets forward-biased switching and reverse-biased clamping only.
Can BAS16B5000 be used in 5 V logic-level translation circuits?
Yes - with VF = 715 mV at 1 mA and trr = 4 ns, it provides minimal voltage drop and negligible delay in open-drain or wired-OR logic translation (e.g., I²C pull-up isolation). It must be paired with appropriate series resistors to limit peak current during level transitions.
